Deception Sneak Peek: Has Joanna Compromised the Case?

Now that Joanna (Meagan Good) finally has her sights on a main suspect in the murder of her former best friend on NBC's Deception, will her past come back to haunt her?

At the end of this week's episode, a photograph led Joanna to conclude that Vivian Bowers' brother, Julian (Wes Brown), is the one who killed her. But on Monday's episode, Joanna's partner (professionally and sometimes personally) Will (Laz Alonso) tells her that the affair she had with Julian 17 years prior may have compromised their case.
